drm/i915/sdvo: Implement proper HDMI audio support for SDVO
Our SDVO audio support is pretty bogus. We can't push audio over the
SDVO bus, so trying to enable audio in the SDVO control register doesn't
do anything. In fact it looks like the SDVO encoder will always mix in
the audio coming over HDA, and there's no (at least documented) way to
disable that from our side. So HDMI audio does work currently on gen4
but only by luck really. On gen3 it got broken by the referenced commit.
And what has always been missing on every platform is the ELD.
To pass the ELD to the audio driver we need to write it to magic buffer
in the SDVO encoder hardware which then gets pulled out via HDA in the
other end. Ie. pretty much the same thing we had for native HDMI before
we started to just pass the ELD between the drivers. This sort of
explains why we even have that silly hardware buffer with native HDMI.
$ cat /proc/asound/card0/eld#1.0
-monitor_present 0
-eld_valid 0
+monitor_present 1
+eld_valid 1
+monitor_name LG TV
+connection_type HDMI
+...
This also fixes our state readout since we can now query the SDVO
encoder about the state of the "ELD valid" and "presence detect"
bits. As mentioned those don't actually control whether audio
gets sent over the HDMI cable, but it's the best we can do. And with
the state checker appeased we can re-enable HDMI audio for gen3.

The AVI infoframe readout code currently issues a

a problem since we left the index pointing at the AVI infoframe

drm/i915: Report all objects with allocated pages to the shrinker
Currently, we try to report to the shrinker the precise number of
objects (pages) that are available to be reaped at this moment. This
requires searching all objects with allocated pages to see if they
fulfill the search criteria, and this count is performed quite
frequently. (The shrinker tries to free ~128 pages on each invocation,
before which we count all the objects; counting takes longer than
unbinding the objects!) If we take the pragmatic view that with
sufficient desire, all objects are eventually reapable (they become
inactive, or no longer used as framebuffer etc), we can simply return
the count of pinned pages maintained during get_pages/put_pages rather
than walk the lists every time.
The downside is that we may (slightly) over-report the number of
objects/pages we could shrink and so penalize ourselves by shrinking
more than required. This is mitigated by keeping the order in which we
shrink objects such that we avoid penalizing active and frequently used
objects, and if memory is so tight that we need to free them we would
need to anyway.

not considering stolen and foreign objects.

drm/i915: Track the purgeable objects on a separate eviction list
Currently the purgeable objects, I915_MADV_DONTNEED, are mixed in the
normal bound/unbound lists. Every shrinker pass starts with an attempt
to purge from this set of unneeded objects, which entails us doing a
walk over both lists looking for any candidates. If there are none, and
since we are shrinking we can reasonably assume that the lists are
full!, this becomes a very slow futile walk.
If we separate out the purgeable objects into own list, this search then
becomes its own phase that is preferentially handled during shrinking.
Instead the cost becomes that we then need to filter the purgeable list
if we want to distinguish between bound and unbound objects.

drm/i915: add force_probe module parameter to replace alpha_support
The i915.alpha_support module parameter has caused some confusion along
the way. Add new i915.force_probe parameter to specify PCI IDs of
devices to probe, when the devices are recognized but not automatically
probed by the driver. The name is intended to reflect what the parameter
effectively does, avoiding any overloaded semantics of "alpha" and
"support".
The parameter supports "" to disable, "<pci-id>,[<pci-id>,...]" to
enable force probe for one or more devices, and "*" to enable force
probe for all known devices.
Also add new CONFIG_DRM_I915_FORCE_PROBE config option to replace the
DRM_I915_ALPHA_SUPPORT option. This defaults to "*" if
DRM_I915_ALPHA_SUPPORT=y.
Instead of replacing i915.alpha_support immediately, let the two coexist
for a while, with a deprecation message, for a transition period.

drm/i915/gtt: Avoid overflowing the WC stash
An interesting issue cropped with making the pagetables be allocated and
freed concurrently (i.e. removing their grandeous struct_mutex guard)
was that we would overflow the page stash. This happens when we have
multiple allocators grabbing WC pages such that we fill the vm's local
page stash and then when we free another page, the page stash is already
full and we overflow.
The fix is quite simple: to check for a full page stash before adding
another. This results in us keeping a vm local page stash around for
much longer, which is both a blessing and a curse.

Revert "drm/i915: Expand subslice mask"
This reverts commit
1ac159e23c2c ("drm/i915: Expand subslice mask"),
which kills ICL due to GEM_BUG_ON() sanity checks before CI even gets a
chance to do anything.
The commit exposes an issue in commit
1e40d4aea57b ("drm/i915/cnl:
Implement WaProgramMgsrForCorrectSliceSpecificMmioReads"), which will
also need to be addressed.
There's a proposed fix [1], but considering the seeming uncertainty with
the fix as well as the size of the regressing commit (in this context,
the one that actually brings down ICL), this warrants a revert to get
ICL working, and gives us time to get all of this right without
rushing. Even if this means shooting the messenger.

drm/i915: Refactor sseu helper functions
Move functions to intel_sseu.h and remove inline qualifier.
Additionally, ensure these are all prefixed with intel_sseu_*
